What is the purpose of the national mathematical modeling competition for college students? Innovation consciousness and team spirit focus on participating in fair competition? .
The test questions and excellent papers of the competition are displayed in? National Mathematical Modeling Competition for College Students? Official website. Take 20 17 as an example. There are four test questions, namely: Question A -CT Calibration and imaging of CT system parameters; Question b-taking pictures to make money? Task pricing; C- color and substance concentration identification; Question d- arrangement of inspection line.
The specific types of questions are introduced as follows: the structure of competition questions generally consists of three parts: the real background, some hypothetical conditions and questions to be answered.
The first part will involve new problems in the fields of society, economy, management, life, environment, natural phenomena, engineering technology and modern science, and will give a more accurate question. But in general, the coverage is very wide, which requires participants to dabble in various mathematical models.
The second part will be divided into the following situations: only conceptual assumptions such as processes and rules are given, and relevant data are not given; Give the statistical data obtained from the actual samples; Give graphs and parameters; There are also some supplementary assumptions that can be freely played, and contestants can collect data according to their own model needs.
In the third part, there are usually several questions to be answered. Usually, some questions need to give definite answers, that is, the mathematical results obtained according to the model; There will be divergence problems later, and the scheme needs to be optimized.
